TL;DR: The atmospheric Cherenkov gamma-ray telescope MAGIC, designed for a low-energy threshold, has detected very-high-energy gamma rays from a giant flare of the distant Quasi-Stellar Radio Source 3C 279, at a distance of more than 5 billion light-years.

TL;DR: The detection of variable gamma-ray emission above 100 gigaelectron volts from the microquasar LS I 61 + 303 is reported, which suggests that the emission is periodic.

TL;DR: By developing a new electronic trigger, the threshold of the MAGIC telescope is lowered, revealing a relatively high cutoff energy in the phase-averaged spectrum, which indicates that the emission occurs far out in the magnetosphere, hence excluding the polar-cap scenario as a possible explanation of the measurement.

TL;DR: The MAGIC Cerenkov telescope has observed very high energy (VHE) gamma-ray emission from the active galactic nucleus 1ES 1959+650 during 6 hr in 2004 September and October.

TL;DR: In this paper, the angular distribution of reconstructed gamma-ray arrival directions around the source is broader than for a point-like source, and upper limits on the extended emission around the bright blazars Mrk 421 and Mrk 501 using the MAGIC telescope data are presented.
